Sun and Marco Rosoldi}, journal={Environmetrics}, year={2018}, volume={30} }
Satellite product validation is a key to ensure the delivery of quality products for climate and weather applications. To do this, a fundamental step is the comparison with other instruments, such as radiosonde. This is especially true for essential climate variables such as temperature and humidity.
